Figure 11. 50-MHz profile from three concatenated transects (CR94-53, 98, 69). Subpermafrost
ground water was found only at the northern end. The interpreted permafrost horizon depicted
with question marks is speculative. Arrows in radar traces indicate bedrock reflectors.
Figure 12. 50-MHz profile of south to north transect 94-61, which lies west of the landfill (see
Fig. 6). Borehole locations are shown. The lower profile shows the interpretation of the borehole
and GPR data. The bottom of permafrost was encountered only at the southern end. Perma-
frost appears to extend into bedrock along most of this line. Arrows in radar traces indicate
bedrock reflectors.
